How to roll rice straw. This model still don't like the picture below. This model can make the straw can keep for long time. The Straw can use for cow feed and can use for other purposes like for mushroom media.

Tree Growth
Growth of a tree occurs from division of cells in the meristematic tissue in the cambium and the tips of the branches and roots. Cambial cell division results in an increase in the tree diameter. The xylem cells added to the stem usually differentiate into thin walled springwood and thick walled summerwood that produce the annual rings visible in cross sections of most tree trunks from temperate areas. The meristems associated with the crown produce elongation of the branches, resulting in increases in tree height.

Threes are potentially immortal because meristematic tissue is retained throughout the life of the tree. Death usually result from some environment agent, such as fire, wind, lightning, drought, or human cutting, or from a biological cause, such as disease or insect attack. As a tree ages it may become more susceptible to insect, pest or diseases, such as bark beetles or fungal root rots, which contribute directly or indirectly to its death. Most trees actually die to several causes.

Ecology and Distribution
Moisture, temperature and nutrient condition are the most important environmental factor affecting the establishment and growth of tree species. Forest is widely distributed in the temperate and tropical regions of the world and are a reflection of favorable moisture and temperature regimes in these areas. Some notable forest regions in North America are the pine forests of the southeastern states, the deciduous hardwood firsts of the northeastern and Great Lakes region, the mixed coniferous forests of the Rocky Mountains and Sierra Nevada, and the dense coniferous forests of the Pacific Coast.

Tree species tolerate different environmental conditions. Trees grow more slowly, attain smaller dimensions, and are often more widely spaced in cold or arid regions. Cold temperatures, short growing seasons, and heavy snow prevent the growth of trees at high elevations and high latitudes. Moisture stress typically limits tree growth at lower timberlines, such as those adjacent to grasslands or deserts.

How to plant Mahogany plant in the vast empty land, but we don't have time. Mahogany seed is different with other kind of seed, mahogani seed actually have wing that can spreed far, if there is a wind to blow the seed. We can spreed the seed by helly in a wide area of empty land in order can planting mahogany tree with efficient time.

In the right time and in the right place, we spreed all of mahogany seed to the empty land. Better time to spreed all of our seed may be in a rainy season. Country is responsible for this planting because many forest in Sumatra and Kalimantan have deforested because people didn't responsible after trim trees. Government can use helicopter to spread the seed to all over the land in the right time, people will don't care what to spread in the land because it rainy season. After the rainy season hope the seed already grown.

Government should have many option to grow some trees in the forest with efficient time, because they don't have time for seeding in a huge land without enought resources. Only use a modern equipment they can cover all the land in Indonesia like forestry must have helicopter to seed. This method must be considerated by Government or any other option, please review.

Indonesian rice production is increase per ha, the quality of rice and the cultivation management can make the production ammount can be increased. As the new technology applied in rice field of Indramayu - North java, the production of rice can increase from 8 ton per hectare become 9.3 ton per hectar. This rising can make us please, even we know in the near future we will need additional rice from outside country. The number of civilization is always increase and this need more rice overall.
